  • Patent number: 9812599
    Abstract: A method of forming a semiconductor material of a photovoltaic device that includes providing a surface of a hydrogenated amorphous silicon containing material, and annealing the hydrogenated amorphous silicon containing material in a deuterium containing atmosphere. Deuterium from the deuterium-containing atmosphere is introduced to the lattice of the hydrogenated amorphous silicon containing material through the surface of the hydrogenated amorphous silicon containing material. In some embodiments, the deuterium that is introduced to the lattice of the hydrogenated amorphous silicon containing material increases the stability of the hydrogenated amorphous silicon containing material.

  • Patent number: 9711416
    Abstract: A semiconductor fin including a single crystalline semiconductor material is formed on a dielectric layer. A semiconductor shell including an epitaxial semiconductor material is formed on all physically exposed surfaces of the semiconductor fin by selective epitaxy, which deposits the semiconductor material only on semiconductor surfaces and not on dielectric surfaces. The epitaxial semiconductor material can be different from the single crystalline semiconductor material, and the semiconductor shell can be bilaterally strained due to lattice mismatch. A fin field effect transistor including a strained channel can be formed. Further, the semiconductor shell can advantageously alter properties of the source and drain regions, for example, by allowing incorporation of more dopants or by facilitating a metallization process.

  • Patent number: 9679775
    Abstract: An approach to providing a method of forming a dopant junction in a semiconductor device. The approach includes performing a surface modification treatment on an exposed surface of a semiconductor layer and depositing a dopant material on the exposed surface of the semiconductor layer. Furthermore, the approach includes alloying a metal layer with a dopant layer to form a semiconductor device junction where the semiconductor layer is composed of a Group III-V semiconductor material, the surface modification treatment occurs in a vacuum chamber to remove surface oxides from the exposed surface of the semiconductor layer, and each of the above processes occur at a low temperature.

  • Patent number: 9590054
    Abstract: Embodiments of the present invention provide semiconductor structures and methods for making the same that include a boron nitride (BN) spacer on a gate stack, such as a gate stack of a planar FET or FinFET. The boron nitride spacer is fabricated using atomic layer deposition (ALD) and/or plasma enhanced atomic layer deposition (PEALD) techniques to produce a boron nitride spacer at relatively low temperatures that are conducive to devices made from materials such as silicon (Si), silicon germanium (SiGe), germanium (Ge), and/or III-V compounds. Furthermore, the boron nitride spacer may be fabricated to have various desirable properties, including a hexagonal textured structure.

  • Patent number: 9576964
    Abstract: At least one dielectric pad layer is formed on a semiconductor-on-insulator (SOI) substrate. A deep trench is formed in the SOI substrate, and a combination of an outer electrode, a node dielectric, and an inner electrode are formed such that the top surface of the inner electrode is recessed below the top surface of a buried insulator layer of the SOI substrate. Selective epitaxy is performed to fill a cavity overlying the inner electrode with an epitaxial semiconductor material portion. A top semiconductor material layer and the epitaxial semiconductor material portion are patterned to form a fin structure including a portion of the top semiconductor material layer and a portion of the epitaxial semiconductor material portion. The epitaxial semiconductor material portion functions as a conductive strap structure between the inner electrode and a semiconductor device to be formed on the fin structure.

    Abstract: Ion implantation to change an effective work function for dual work function metal gate integration is presented. One method may include forming a high dielectric constant (high-k) layer over a first-type field effect transistor (FET) region and a second-type FET region; forming a metal layer having a first effective work function compatible for a first-type FET over the first-type FET region and the second-type FET region; and changing the first effective work function to a second, different effective work function over the second-type FET region by implanting a species into the metal layer over the second-type FET region.
